1-phenyl-4,4-dimethyl-1,4-phosphasilacyclohexane and its selenide

1-phenyl-4,4-dimethyl-1,4-phosphasilacyclohexane was formed upon the photochemical addition of phenylphosphine to dimethyl(divinyl)silane and gave 1-phenyl-4,4-dimethyl-1-seleno-1,4-phosphasilacyclohexane upon reaction with elemental selenium. NMR spectroscopy indicated that 1-phenyl-4,4-dimethyl-1,...

Beschreibung
Zusammenfassung:	1-phenyl-4,4-dimethyl-1,4-phosphasilacyclohexane was formed upon the photochemical addition of phenylphosphine to dimethyl(divinyl)silane and gave 1-phenyl-4,4-dimethyl-1-seleno-1,4-phosphasilacyclohexane upon reaction with elemental selenium. NMR spectroscopy indicated that 1-phenyl-4,4-dimethyl-1,4-phosphasilacyclohexane and 1-phenyl-4,4-dimethyl-1-seleno-1,4-phosphasilacyclohexane exist in the chair conformation with predominance of the conformer with axial orientation of the unshared electron pair of the phosphorus atom.
